A model for an aquatic ecosystem
Han Li Qiao, Ezio Venturino
An ecosystem made of nutrients, plants, detritus and dissolved oxygen is presented. Its equilibria are established. Sufficient conditions for the existence of the coexistence equil…
An epidemiological model of viral infections in a Varroa-infested bee colony: the case of a bee-dependent mite population size
Sara Bernardi, Ezio Venturino
In recent years the spread of the ectoparasitic mite Varroa destructor has become the most serious threat to worldwide apiculture. In the model presented here we extend the bee pop…
Interplay of network dynamics and ties heterogeneity on spreading dynamics
Luca Ferreri, Paolo Bajardi, Mario Giacobini +2
The structure of a network dramatically affects the spreading phenomena unfolding upon it. The contact distribution of the nodes has long been recognized as the key ingredient in i…
Ecoepidemics with a nonlinear disease incidence
Ezio Venturino
We present two new models for interacting populations subject to a transmissible disease. The novelty lies in the assumption that herd behavior influences the disease incidence, ra…
Ecoepidemics with infected prey in herd defense: the harmless and toxic cases
Elena Cagliero, Ezio Venturino
We consider a predator-prey population model with prey gathering together for defense purposes. A transmissible unrecoverable disease affects the prey. We characterize the system b…
Chaos control via feeding switching in intraguild predation systems
Joydev Chattopadhyay, Nikhil Pal, Sudip Samanta +1
In the present paper we study a tri-trophic Lotka-Volterra food web model with omnivory and predator switching. We observe that if the intensity of predator switching increases the…
